PENHOLDER.

T all whom it may concern:

Be it known that I, JAMES A. BALDWIN, a citizen of the United States ofAmerica, residing at Maynard, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Penholders,of which the following is a specification.

This invention relates to pen holders, and one of the principal objectsof the same is to provide simple and eiiicient means for releasing andejecting the pen when it is re quired to substitute a new pen point.

Another object of the invention is to provide a pen holder adapted toreceive pens whose shanks vary in size and curvature, and an ejectoradapted to push out any such pen whenever it is required to substitute anew one for one that has become worn or injured.

These and other objects may be attained by means of the constructionillustrated in the accompanying drawing, in which,

Figure l is a perspective view of a pen holder made in accordance withmy invention. Fig. 2 is a longitudinal section of the lower end of thepen holder. Fig. 3 is a sectional view on the line 33 of Fig. 2. Fig. 4is a sectional view on the line H of Fig. 2, looking in the directionindicated by the arrow. Fig. is a view of the ejector, the head of whichis shown in section.

Referring to the drawings, the numeral 1 designates the stafl and 2 isthe ferrule which is usually a cylinder secured on the staif. In thepresent case I cut away the lower portion of the outer end of thisferrule so as to leave the upper semi-cylindrical portion remaining, andthe two edges of this portion I bend inwardly and upwardly into lips 3which receive the edges of the pen 4 as best seen in Fig. 4. The sizeand curvature of the ferrule 2 is that adapted to a pen having a shankof the usual shape, but by making the lips 3 as shown it will be obviousthat a pen whose shank is some what narrower or whose curvaturetransversely is on a greater are than shown can be accommodated byinserting it into the outer end of the ferrule 2 with its edges behindthe lips 3. Perhaps it would not fit so accurately then in the ferruleas shown in Specification of Letters Patent.

Fig. 4:, especially if its center (at the top in that view) wereflattened out a little more than illustrated, but with its edges engagedbehind the lips its own tendency to resume its normal curvature wouldcause it to be held with suflicient strength for writing purposes.

The present invention contemplates the employment of an ejector adaptedfor use with any pen which can be inserted in the holder, and theejector head itself serves as a finger piece upon which the writer canplace the tip of his index finger while using the device. To this endsaid head is a button 6 having a concave face '7, and the body 9 of theejector is a block standing within the bore of the ferrule 2 and curvedon its upper face to conform with the curvature thereof as best shown inFig. 3. The block and head are connected by two pins or shanks 8 whichextend upward from the block through a straight slot 5 extendinglongitudinally along the top of the ferrule, and are secured to thebutton 6 in any suit-- This ejector in the normal position of partsstands where the tip of the fore finger w ll rest in the concavity 7 andthe block 9 is then above the inner end of the pen shank. lVhen it isdesired to eject a soiled or worn out pen, it is only necessary to pushthe button downward when the shanks 8 travel in the slot 5 and the block9 impinges behind the shank of the pen and pushes the latter out of theholder. In this action the shape of the block is important. Obviously itmust be narrow enough to move between the lips 3. Its upper face mustfollow the curvature of the bore of the ferrule or else in movingdownward the block might pass under the inner end of a pen shank whichfitted the ferrule closely and its body must have some thickness inorder that it will reliably strike said pen shank even if the lattershould not closely follow the curvature of the ferrule.

I claim:

A pen holder comprising a staff, a ferrule having its upper endcylindrical and fast on the staff and its lower end provided in its topwith a longitudinal slot and having the edges of its lower end bentinward into lips; and an ejector comprising a block within the ferrulewith its upper face curved to In testimony whereof I affix my signatureconform with the bore thereof and its width In presence of tWOwltnesses. less than the space between said lips, a but 1 T ton exteriorto the ferrule and having a con- JAlMES BALD" 5 cave face, and twonarrow shanks connect- WVitnesses:
